[PATCH v3 00/14] pxa_camera transition to v4l2 standalone device

Hi Hans,

We're leaving the domain of the RFC to a proper submission.

This is very alike to what you reviewed earlier, the code is very close, and :
- the split between patches is done to better isolate cleanups from real code
- start_streaming() was implemented
- your remarks have been taken into account (please double-check if you're
happy with it)
- v4l2-compliance -f and v4l2-compliance -s were run without any error, and 6 warnings
warn: v4l2-test-formats.cpp(713): TRY_FMT cannot handle an invalid pixelformat.
warn: v4l2-test-formats.cpp(714): This may or may not be a problem. For more information see:
warn: v4l2-test-formats.cpp(715): http://www.mail-archive.com/linux-media@vger.kernel.org/msg56550.html
- soc_camera is not touched anymore
- the driver is still functional from a capture point of view as before
(ie. taking a real picture)

I'm still relying on soc_mediabus, hence the not-so-nice Makefile diff hunk.

The only architecture which will have its deconfigs impacted is pxa, under my
maintainance, and once the review is finished and you have a landing cycle I'll
complete with a simple serie on the pxa side (defconfig + platform data).

I've also put the whole serie here if you want to fetch and review from git directly :
- git fetch https://github.com/rjarzmik/linux.git work/v4l2

Happy review.
